| To RHC.{R. H. Coverley - Production Engineer} X411 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}7/KW.15.11.34. Ground Textolite Gears on the Bentley. We note that the ground steel gears to mesh with the Textolite on B-10 unit have a very coarse finish. As it is intended that these gears shall be a model of what we may expect with regard to durability if we go into production with this material, we are anxious that they should have a representative finish and a good bedding.
